Laid to rest, then laid to rest again. More definitely the second time though.
Burning a body to ashes without a proper crematorium would have involved quite a bit of effort I suspect, and be a bit hard to keep quiet in a small place.
Apparently the neighbours knew what was going on though, and even helped. The sons were hardly desecrating a corpse on the sly and the victims next of kin were the instigators. I wonder what law these men broke?
